Question 1

Question
There are [blank_start]3[blank_end] types of rock
Answer
  • 3

Question 2

Question
Igneous rocks are formed by [blank_start]magma[blank_end] (melted underground rock) which is pushed up to the [blank_start]crust[blank_end] and often out [blank_start]volcanoes[blank_end]
Answer
  • magma
  • crust
  • volcanoes

Question 3

Question
Igneous rocks contain various [blank_start]minerals[blank_end] in randomly arranged [blank_start]interlocking crystals[blank_end]. The [blank_start]size[blank_end] and [blank_start]texture[blank_end] of the crystals depend on speed of cooling
Answer
  • minerals
  • interlocking crystals
  • size
  • texture

Question 4

Question
There are 2 types of igenous rock- [blank_start]extrusive[blank_end] and [blank_start]intrusive[blank_end]
Answer
  • extrusive
  • intrusive

Question 5

Question
Extrusive igneous rocks cool [blank_start]quickly[blank_end] [blank_start]above[blank_end] ground
Answer
  • quickly
  • above

Question 6

Question
Intrusive igneous rocks cool [blank_start]slowly[blank_end] [blank_start]below[blank_end] ground
Answer
  • slowly
  • below

Question 7

Question
Igneous rocks don't form [blank_start]fossils[blank_end] as any [blank_start]fossils[blank_end] wil have melted to form [blank_start]magma[blank_end] in the original rock
Answer
  • fossils
  • fossils
  • magma

Question 8

Question
Sedimentary rocks are formed by layers of [blank_start]sediment[blank_end], which are [blank_start]rock fragments[blank_end] that are deposited
Answer
  • sediment
  • rock fragments

Question 9

Question
To form sedimentary rocks, over time the [blank_start]layers[blank_end] are [blank_start]cemented[blank_end] together by [blank_start]minerals[blank_end] that act as glue
Answer
  • layers
  • cemented
  • minerals

Question 10

Question
To form sedimentary rocks, the weight of the [blank_start]sediments[blank_end] on top squashes the [blank_start]sediments[blank_end] at the botoom. This is called [blank_start]compaction[blank_end]
Answer
  • sediments
  • sediments
  • compaction

Question 11

Question
[blank_start]Fossils[blank_end] can form in the sediments. this is the long dead remains of animals and plants
Answer
  • Fossils

Question 12

Question
Metamorphic rocks are made by the result of [blank_start]heat[blank_end] and [blank_start]increased[blank_end] pressure acting on existing [blank_start]rocks[blank_end] over a [blank_start]long[blank_end] period of time
Answer
  • heat
  • increased
  • rocks
  • long

Question 13

Question
Metamorphic rocks may have tiny [blank_start]crystals[blank_end] and some have [blank_start]layers[blank_end]
Answer
  • crystals
  • layers

Question 14

Question
Metamorphic rocks are always made from [blank_start]interlocking[blank_end] crystals
Answer
  • interlocking

Question 15

Question
Metamorphic rocks usually have different properties to the [blank_start]rocks[blank_end] from which [blank_start]they were made from[blank_end]
Answer
  • rocks
  • they were made from

Question 16

Question
Metamorphic rocks are never made from [blank_start]molten[blank_end] rock
Answer
  • molten

Question 17

Question
Metamorphic rocks rarely contain [blank_start]fossils[blank_end]. The don't normally usrvive the [blank_start]heat[blank_end] and [blank_start]pressure[blank_end]
Answer
  • fossils
  • heat
  • pressure

Question 18

Question
Metamorphic rocks can be heated up by the movement of [blank_start]tectonic plates[blank_end] or [blank_start]magma[blank_end]
Answer
  • tectonic plates
  • magma

Question 19

Question
The higher temperature and pressure of rock when formed, the crystal size [blank_start]increase[blank_end] and the thickness of layers [blank_start]increase[blank_end]
Answer
  • increase
  • increase
